Alternate between 2 or more colors based on the number of console writes:

Console colors can be set back to their defaults using the Colorful.Console.ReplaceAllColorsWithDefaults function.

Individual colors in the console's color palette can be replaced using the Colorful.Console.ReplaceColor function.

Colorful.Console can only write to the console in 16 different colors (including the black that's used as the console's background, by default!) in a single console session. This is a limitation of the Windows console itself (ref: MSDN), and it's one that I wasn't able to work my way around. If you know of a workaround, let me know!

I don't know how well Colorful.Console will work with CLI languages other than C#.
